БМВ М30 е най-дълго произвеждания двигател на БМВ, от 1968 до 1994 г.
М30 Б34MAE/Б32LAE е турбо двигателя на Е23 745! Около 250 конски сили и 380 н.м. По това време (началото на 80-те) Мерцедес 500 е около 220-240 коня и около 400 н.м.

http://en.wikipedia.org/wiki/BMW_M21-Forced induction: By far the most effective means of increasing power output, with tremendous potential available for far less than the cost of a NA stroker engine. A stock engine with head studs will reliably support over 20 psi (1.4 bar) with intercooling, a good tune and a sufficiently large turbine. Standalone injection should be considered mandatory for boost pressures over 1 bar. The bottom ends are very robust and will be the last parts to sustain damage if detonation occurs. The head gasket will fail first, which can crack the cylinder head if the engine is run for very long in that condition. They tolerate a considerable amount of detonation at lower boost pressures but become more sensitive as boost increases. The driver must listen carefully to the engine to avoid damage if detonation occurs. Aftermarket MLS head gaskets resist detonation slightly better which can result in damage to the piston ring lands in the event of severe, sustained detonation. Even slight detonation is audible with a full exhaust system while moderate detonation can usually be heard over an "open dump" wastegate.
